If you provide free housing for everyone who refuses to work, eventually no one will work and the system will collapse. Then what?
The majority of the homeless people I've spoken with have just been swallowed up with some hard knocks in their lives. Divorce, family illness, addictions, loss of job, disaster, abuse, etc. has cracked their world and often their mental stability.
Perhaps along with the housing, there would also be people who volunteer their time to counsel those with depression, grief or addictions, or help the homeless prepare for the job market, or tutor in various areas to help them better their chances for good employment.
Just saying.
